At Prosidyan, the engineers redline the latest version of a document online using track changes. Before redlining, the engineer will create a DCO(document change order) with new revision and why changes are being made.The document record must be attached to a change notice document type in order to be considered as design change request. The change notice is sent to document control which approves or disproves of the changes. Once document control approves of the changes then a head from each department is obligated to sign off on the new changes. The documents is then trained for whichever department it is required for and then the document is released to be used.
